Chris Daigle, Product Manager
Voice AI isn't 100%, but Vapi is easy to use and definitely some of the best voice AI capabilities I've seen...

Note: There are no reviews for Vapi on G2, Capterra, or Trustpilot at this time—users should be cautious and consider this when evaluating broader sentiment.

PolyAI

"Exceptional capability"
Anonymous Reviewer (G2)
I loved PolyAi for its exceptional capability to automate client calls. Their customer support is commendable. The interface is simple and very user friendly...

"Competitor offerings seem robotic"
Anonymous Reviewer (G2)
The assistant itself is lifelike and constantly learning... In comparison, competitor offerings seem robotic make customers feel like they are not being cared for...

Note: While there’s no single average rating number provided by G2 or other platforms in public summaries, all available written feedback points toward a strong reputation among enterprise users.

What users are saying about Ringly.io:

However, I must express that the product has shown significant promise. When compared to competitors, it stands out significantly ahead.

Who Ringly.io is best for…

  • Shopify stores that need phone support

Why Ringly.io is a Better Choice

Best for Shopify stores looking for the best way to offer 24/7 AI phone support at a fraction of the cost.

How it went when I tried setting up Ringly:

After I installed the Shopify app, the only thing I had to do was to upload my data to the knowledge base. (website was uploaded automatically)

After I did that, I could already speak to my agent via a web call.

Setting it live was as simple as picking a phone number with my area code from the dashboard. I was able to connect the number with 1 click. (The number is also free and included)

There was not really anything else to the setup.

They claim that out of the box, their agents resolve an average of 73% of support calls. They back that up with data from over 2,100 active Shopify stores.

Signup -> onboarded took only 4 minutes and 12 seconds. Most of that time was spent waiting for the knowledge to be uploaded.

Over the first 2 weeks I used it (14-day free trial), it resolved 76% of my calls on its own.

The rest of the calls were escalated to a support ticket by my agent.

(update: the more calls you get, the smarter it gets. As of today, my resolution rate is 79%.)

Standout Features (pros):

  • Very easy setup (almost none)
  • Pay on results pricing

Pricing is on a results basis; you don't pay until your agent has at least a 60% resolution rate

Shopify integration is native. It will allow your agent to solve order status and refund requests on the phone.

Reviews are overall very positive, mainly because of the results-based pricing. If you don't pay unless you get results, every customer gets results.

Cons:

  • Phone support only

What’s unique about Ringly is that it is the first AI phone support tool built for Shopify.

Editors note: Ringly.io opened 5 spots for Shopify stores to pay $0 until AI resolves 60% of your support calls. You can book a call to claim it.

Final Thoughts: Which AI Voice Platform Comes Out on Top?

  • Vapi is perfect for developers and enterprise teams that need low-latency performance, millions of concurrent calls, and deep backend customization. If you've got engineering support, it's incredibly flexible.
  • PolyAI excels in large-scale customer service across industries, offering world-class NLU and lifelike dialogue out-of-the-box, especially for businesses with complex needs and larger budgets.
  • Ringly.io is ideal for fast-moving Shopify brands.
